I have been lucky enough to procure a copy of the Frankie Howerd
series "Whoops Baghdad". There is one episode in which Janet appears
as a slave for sale. Her character name was Gigantima and she is
described as Miss Greater London! There are two or three scenes in
which she appears and she looks excellent. Watch out for it in case
it gets repeated on UK Gold or somewhere. The actual episode is
called "A Cargo of Crumpet".
